摘要
利用超声波技术对蜂蛹脂肪的提取工艺进行了研究,并对蜂蛹脂肪酸的成分进行了分析。结果表明,超声波提取蜂蛹脂肪时间短,效果好。最佳提取工艺条件为:提取溶剂为石油醚,超声波强度34W/cm2,超声波处理时间25min,料液比1∶20。蜂蛹脂肪的一次提取率为97.3%。蜂蛹脂肪约占干物质总量的26.09%,含5种脂肪酸,含量最高的是油酸,占脂肪酸总量的43.27%,其它成分的含量相对较少。
The ultrasound extraction technology and composition analysis of honeybee pupa fat were studied in this test. The results showed that it took short time to extract honeybee pupa fat with ultrasound treatment and had a good effect. The optimum extracting condition was ultrasound intensity 34 W/cm^2 ,extracting time 25 min,ratio of materials to solvent 1 ： 20 with petroleum ether as the solvent. The fat extraction rate of honeybee pupa was 97.3%. The fat content was 26.09% in dry honeybee pupa and there were five fatty acids in the fat. The oleic acid content was 43.27% in total fatty acids and was highest compared with other components.
